Abstract (en)
[origin: EP2551300A1] An object of the present invention is to provide an EVOH-containing resin composition which has superior appearance characteristics and long-run workability in melt molding and enables occurrence of yellowing etc. , in melt molding to be inhibited particularly, even in melt molding at high temperatures of, for example, no less than 260°C. Further provided is a multilayered structure molded from the composition. The present invention provides a resin composition containing (A) an ethylene-vinyl alcohol copolymer, (B) a carboxylic acid and/or a carboxylate ion, and (C) a metal ion, wherein the component (B) includes (B2) a multivalent carboxylic acid and/or a multivalent carboxylate ion, and the molar ratio (B2/C) of the multivalent carboxylic acid and the multivalent carboxylate ion (B2) to the metal ion (C) is 0.002 or greater and 2 or less.
